As we stated in the Overview chapter, the architecture of the QNX Neutrino RTOS consists of a small microkernel and some number of cooperating processes. We also pointed out that your applications should be written the same way—as a set of cooperating processes.
In this chapter, we'll see how to start processes (also known as creating processes) from code, how to terminate them, and how to detect their termination when it happens.
For another perspective, see the Processes and Threads and Message Passing chapters of Getting Started with QNX Neutrino.
